I was what they called a sky pioneer in that I had a satellite system right at the very beginning , late 80s
The astra satellite was a new thing , on one of the channels they had a advert running 24/7 showing clips from various European TV shows on a loop
One Saturday morning I was walking past a major high street TV retailer when I noticed they had this ad running on a a load of TVs in the window , I thought , no it can't be the same , it must be edited on a vhs tape
But no I waited and there it was , one clip was for a German pron channel, the scene was a camera in a helicopter which zoomed into a house window where a woman on her knees was making a man very happy, uncensored, it was only for a couple of seconds but yes, a bj in a shop window
I went into the shop and asked if they'd watched it all the way through
no it's only an advert for astra
So I told them and they watched it , 10 minutes later the manager was running to the back of the shop to turn it off.
